Application fled Kay 4, 1927. serial No. 188,688.

This invention has reference to washing machines and particularly tothat type, in which is employed a centrifugal extractor for removing thefree water from the clothin or other materials by centrifugal action,and ischarging such water onto a manually and circumferentiallyadjustable drain board for directing such water into the washing tub orother receptacle, and which also functions to catch the drippings fromclothin or other materials assed from the tub or 0t er receptacle tosaid extractor.

The invention comprehends a housing mounted at the head of the extractorin a manner to adapt it to be manually and ciroumferentially adjustedabout the extractor, whereby to selectively position the drain boardover, and to direct water extracted from clothing or other materials, tothe washing tub or other receptacle or receptacles; and it is theprincipal object of th1s 1nvention to provide a new and novel mountm forsuch housing whereby it is placeable an removable from its support in apredetermined yposition circumferentially of its support; means beingprovided to prevent wabbhng, rattling or chattering of t e housing onits support and means being also provided for locking the housing indifierent circumfer- 30 ential positions on its support.

That the invention may be more fully understood, reference is ha to theaccompan ing drawings illustrating a preferred embo 1- ment of theinvention, in which Fig. 1 is a plan view on a. greatly reduced scale,of so much of a ;washing machine, including the extractor, as willillustrate the embodiment of my invention, the housing and its drainboard shown in full and dotted lines in two of its circumferential1positions;

n the rawings I have illustrated only so much of a washin machineincluding washing tub, centrifuga extractor and supporting frame as willshow the practical embodiment of my invention. In Figures 1 and 2 thereis illustrated by dotted hnes a receptacle to show the adaptability ofmy invention in the passage of clothing or other materials into theextractor from a washing tub and other receptacle and the discharge ofwater expelled from the extractor into such tub or receptacle.

The washing tub, only a part of which is shown, is designated 1 having awashing ele-. ment 2 adapted to be operated from a shaft 3 rotatably10urnaled through the bottom of said tub. The head frame 4 forthe tub '1terminates in a laterall extended rin -like extension 5 the axis 0 whichwhile ing spaced at a suitable distance from one side of the tub is alsoofi-set from a line extending transversely through the axis of the tub,whereb to position the extractor closer to one si e of the machine thanthe other for the convenience of the attendant in handlin the washingand drying operation. A stan ard or post 6 supports the extension 5. Thelegs or standards for the tub and connecting braces with the post 6 areomitted.

The ring-like extension 5 of the frame which supports the housin anddrain board connected thereto and w ich is manual] and'circumferentially adjustable thereon is formed or provided with avertically disosed annular flange 7, the peripheral surace of which istapered downwardly and inwardly, as at 8, see Figs. 2 and 6; with theexception that at predetermined, preferabl three points the peripher ofthis flange 1s cut-away, as at 9, to rovi e cut-awa or cutout portionsof suita le length with s oulders 10 at the opposite ends of suchcut-away or 110 cut-out portions. Such an arrangement of ring-likeextension and flange produces or provides an annular shelf portion 11encircling the flange 7 to provide a rest for the water conductinghousing, to be described, and on which the same may be rotated.

The housing to which reference has been made is designated 12 and isbest seen in Figs. 1, 2, 4 and 5, res ectively. Such housing is ofsuitable dept and circular in outline, being of outside diameter equalto the diameter of the ring-like extension 5 with bearing surfacesadapted to rest and rotate on the flange 7 and the shelf portion 11, seeFigs 2 and 7. Said housing has an annular conduit 13, see Figs. 2 and 5,formed by 1ts vertical outside wall 14 in spaced relatlon to acomparatively short upstandinginner wall 15. The outslde wall 14 isformed wlth a depending apron 16 adapted to rest and rotate on the shelfportion 11, see Fig. 7, and the bottom 17- of the condu1t 13, at a pointcoincident with the base of the wall 15, see

also Fig. 5, is formed or provided with an annular shoulder or off-set18 to overlap the flange 7, whereby the bottom 17 rests and rides on thetop of said flange 7 with the apron 161 ing without and next adJacentthe outside 0 the ring-like extenslon 5 and the shoulder or ofl-set 18 1ing within and next adjacent the flange 7. n this manner and by thismeans the housing is seated and adapted to be rotated on the extension5. The top of the housing is open, as at 19, and movable therein is acover 20 for the extractor 21; said cover being rotatably connected to asupport 22 hinged at one end to the housing, as at 23, while itsopposite end is adapted to be locked against the housing, by suitablelocking means 24. a

'In the form shown, the housing 12 is provided with a radially extendedshelf portion 25, adapted through rotative movement which may beimparted to the housing 12, to be moved over the tub 1 or over a recetacle A, indicated b the dotted lines in igs. 1 and 2. Over t is shelfportion clothes and other materials may be moved to deposit the same inthe extractor 21, from either the tub I or the receptacle A, orvice-verse, and such shelf will catch drippings and direct the same intothe tub 1 or the receptacle A. The shelf 25 is artitioned to provide aconduit 26 therewit in in communication with the conduit 13 of thehousing and havin a discharge outlet, at its outer end, see ig. 4,whereby water expelled from the receptacle 21 into the conduit 13 of thehousing may be discharged into the tub I or the receptacle A, as it isbelieved will be understood.

The receptacle 21, is of the usual taperedlike container used inmachines of like character and is o ratively'connected .With anoperating sha 27, adapted to be actuated from the same source 0 power,not shown,

bgr the rotation thereof, the water ex t e for operatingthe shaft 3connected with the washing element 2. The n per end of the container orrece tacle 21 is so positioned in relation to the interior of thehousing'12,

that through the centrifugal action setnls reby will overflowor bedischar e over the top thereof, over the wall 15 of t e housing 12 intothe conduit 13 and be conducted thereby to the outlet within the shelfortion 25 forming the drain board, and rom thence into'the tub 1 or thereceptacle A.

Connected to the inner face of the apron 16 of the housing are aplurality of spacing and anti-rattling or anti-chatterin blocks 28, seeFigs. 4 and 5. There are pre erably three of these blocks, which havemner tapered surfaces, as at 29 and their lengths conform to pr'areslightly less than the length of the cutaway or cut-out portions 9 inthe flan e 7 of the housing. Preferably two. of t ese blocks are fixe 1yattached to the apron 16 bylthe removable screws 30 and the remainingblock is preferably laterall movable through and by means of a 100 gscrew 31, see Fi 4 and 5. These blocks are s aced from eac othercircumferentially o the housing to correspond to the spacin of thecut-out or cut-awa portions 9 in the flange 7, so that when the ousin ismade to overlie the extension 5 and the b ocks 28 and cut-out' ortions 9are coincident, the housing may e dropped into assembled position on theextension 5 with the blocks 28 enterin the cut-out portions 9 betweentheshouldere ends 10, and by reason of the inner faces of said blockshavin the same taper as the peripheral surface 8 o the flange thehousing may then be rotated on the e nsion 5 with the tapered faces'ofthe bloc and the tapered surface of the flange being next ad'acent.These blocks will prevent rattling or c attering of the housing'on itssupport during the rapid rotation of the container or receptacle 21. Tolock the housing on its suppo in any of its ad'usted positions, theatten ant W1 1 turn up t e locking screw 31 forcing the block intoimpinging locking engagement with the flange 7. In Fig. 3 the dotteds1t1on of the shelf portion 25 of the housing shows the position itshould be caused to assume when placing or removing said housing fromits support.

The securin means for'the housin will prevent its accidentaldisplacement m rovides a simple and convenient means o as sembly anda"means for fixing the same in adjusted positions, while providing forthe easy removal of the housing for shipping puroses.

What I claim is In a centrifugal extractor, in combination a rotatablereceptacle, a member supported to be manually and circumferentiallyadjusted about said receptacle for receiving water expelled thereby andfor discharging such water at different points about said recep tacle, asupport for said member havin an annular vertically disposed ringprovided with a tapered periphery having cut-out portions atpredetermined points, spacing and non-chatterin blocks carried by thememher and so positioned circumferentially thereof as to be movable inthe cut-out ortions of said ring when placing said mem or on andremoving the same from said support and said blocks having taperedsurfaces correspondin to the taper of the surface of said ring an forpreventing dislodgment of the member from its support when said taperedsurfaces of the ring and blocks are co-adj'acent, and means co-actingwith one of said blocks for locking such block in impinging relationwith the ring of said support for securing said member in differentcircum- 20 ferential positions thereon.

In witness whereof, I have hereunto aflixed my hand this 30th da ofApril, 1927.
